H OT-WATER H EATER.

SPECIFICATION forming part Of Letters Patent No. 532,256, dated January 8, 1895.

Application filed March 3. 189 i- Serial No. 502,228; (No model.)

To all whom it may concern.-

Be it known that I, JOHN HERBERT WYNNE, of the city of Montreal, in the District of Montreal and Province of Quebec, Canada, have invented certain new and useful Improvements in Hot-Water Heaters; and I do hereby declare that the following is a full, clear, and exact description of the same.

This invention relates to hot water heaters built up of sections and has for its object to improve the construction of the water headers of same whereby in the event of damage to any section such section can be shut off or cut out of working connection with the remaining sections and so avoid any necessity for immediately removing this particular inoperative section.

The invention may be said to consist in a water header composed Of a number of inde pendently removable sections arranged so that the water header section of any main section can be removed without disturbing any of the others and allow any suitable diaphragm or cut ofi plate to be placed over the opening leading into the main section, and the header section-replaced, thus preventing any water entering that particular main section while still completing the water header and allowing the remaining sections to continue in use.

For full comprehension however of the in vention, reference must be had to the annexed drawings forming a part of this specification, in which like symbols indicate corresponding parts, and wherein Figure l is a side elevation partly in section of a sectional heater provided with my improved water header; Fig. 2, a sectional view taken on line m m, Fig. 1; and Fig. 3 a detail View of one of the removable sections of the water header.

A is the fire pot section of the usual form of heater built of this section and others A A A A A above it.

The first of fire pot section A is the only one having a part of the water header integral therewith, such partbeing shown at a as forming the lowermost section of the water header, being oblong in horizontal section and provided with flanges b b situated at its ends and flush with its top surface. Superimposed bottom side'and openings e e in its inner side,

the latter to communicate with openingsf in the main sections and those 0 d to allow of communication with every other removable section and so secure an unobstructed vertical water passage from the bottom to the top of the water header.

The several removable sections a a a a a, are held together by any suitable means such as the bolts 9 g passing through corresponding perforations g in the respective flanges of the sections and are further secured to the main sections by other suitable means such as the screw bolts h passing horizontally through apertures j in the back sides and perforations k in the central portions lot the inner sides of the sections a, a a a a preferably into screw threaded eyes m in similar central portions of the sections proper A A A A A the perforations is being preferably oval or oblong in form to allow of adjustment for fitting purposes where required.

The top, bottom and inner sides of the removable sections and the back side of the main sections where the removable sections come in contact with them are of course properly faced and if desired any suitable Washers can be interposed to efiect perfect joints.

It will after the foregoing be readily apparent that in the event of either of the main sections becominginoperative from anycause, the removable water h'eadersection belonging to such main section can be removed as indicated by dotted lines in Fig. 1, by undoing the necessary bolts 9 holding it to the other sections and the screw bolt h'securing it tothe main section, after which any suitable device such as'an impervious plate or washer can be set in place so as to close the openings communicating with the inoperative main section, and the removable section re placed thus cutting out such main section and allowing the water header to resume its functions in connection with the remaining main sections.

What I claim is as follows:

1. In a Water heater having a number of heating sections superimposed and supported one upon the other, a water header comprising a number of sections corresponding in depth with said heating sections, formed separate from said heating sections and from each other, having openings in their inner faces to communicate with similar openings in said heating sections and being removably secured against the face of said heating sections containing said openings, for the purpose set forth.

2. In a water heater having a number of heating sections,superimposed and supported one upon the other, a water header comprising a number of superimposed sections corresponding in depth with said heating sections and independently removablefrom same and from each other, having communicating openings and adapted to be removably secured against the face of such heating sections also having communicating openings, for the purpose set forth.

3. In a water heater having a number of superimposed heating sections, a water header constructed of a number of superimposed sections independently removable from said heating sections and having an unobstructed vertical water passage, for the purpose set forth.

4. In a water heater havinga number of superimposed heating sections, a water header constructed of a number of superimposed separate removable sections communicating with the main sections of the heater and with each other and adapted to allow the removal of one of such sections to allow of the closing of the passage to said main sections and replaced in position without disturbing the remainder of the header sections for the purpose set forth.

5. In a water heater having a number of superimposed heating sections, the combination with such sections having openings forming water inlets in their rear sides, of an individual and independently removable water header section for each main section super imposed one upon the other and communicating with each other and with the inlet in 7. In a water heater, the combination with the main fire pot section A having integral water header section a communicating therewith and presenting an opening in its upper side, and the main sections A A A A A arranged above said fire pot section and having openings forming water inlets in their rear sides,-of the independently removable water back sections a, a a a a arranged above and supported by said water header section a and having openings in their bottom,-top and inner sides to effect an unobstructed water way between all the water header sections and communication thereof with each main section; and means for independently securing said header sections to each other and to said main sections for the purposes set forth.

8. In a water heater, the combination of the main fire pot section A having integral water header section a communicating therewith and presenting an opening in its upper side; the main sections A A A A A arranged above said section A and having openings in their rear sides; the water header sections a. a a a a having openings 0,61 and 6 respectively in their upper, bottom and inner sides, the latter opening e, communicating with the openings in the rear sides of the main sections, and those 0, d, with each other, and each water header section having corresponding perforated flanges as b; vertical bolts passing through such flanges to hold said water-header sections together and bolts passing horizontally through said header sections to secure them to the main sections as set forth.
